=head1 NAME
po4a-updatepo - update the translation (in po format) of documentation
=head1 SYNOPSIS
po4a-updatepo -f E<lt>fmtE<gt> (-m E<lt>master.docE<gt>)+ (-p E<lt>XX.poE<gt>)+
(XX.po are the outputs, all others are inputs)
=head1 DESCRIPTION
The po4a (po for anything) project goal is to ease translations (and more
interestingly, the maintenance of translations) using gettext tools on
areas where they were not expected like documentation.
The C<po4a-updatepo> script is in charge of updating po files to make
them reflect the changes made to the original documentation file. For that,
it converts the documentation file to a pot file, and call L<msgmerge(1)>
on this new pot and on the provided po files.
It is possible to give more than one po file (if you want to update several
languages at once), and several documentation files (if you want to store
the translations of several documents in the same po file).
If the master document has non-ascii characters, it will convert the po files
to utf-8 (if they weren't already), in order to allow non-standard characters
in a culture independent way.
=head1 OPTIONS
=over 4
=item -f, --format
Format of the documentation you want to handle. Use the --help-format
option to see the list of available formats.
=item -m, --master
File(s) containing the master document to translate.
=item -M, --master-charset
Charset of the files containing the document to translate. Note that all
files must have the same charset.
=item -p, --po
Po file(s) to update. If these files do not exist, they are created by
C<po4a-updatepo>.
=item -o, --option
Pass an extra option to the format plugin. See the documentation of each
plugin for more information about the valid options and their meanings.
=item -h, --help
Show a short help message.
=item --help-format
List the documentation format understood by po4a.
=item -V, --version
Display the version of the script and exit.
=item -v, --verbose
Increase the verbosity of the program.
=item -d, --debug
Output some debugging information.
